A Preliminary Study of Correlates of Premature Birth and Their Influence on Cortisol Levels in Young Children

OBJECTIVE

The HPA-axis is programmed during early infancy, but a lot is unknown about the programming of the HPA-axis in prematurely born or small for gestational age (SGA) children. Therefore, the aim of this preliminary study was to investigate the influence of prematurity and variables associated with birth on cortisol levels in young children.

METHODS

Cortisol was measured in a cross-sectional design in 38 premature born participants (<37 weeks of gestation), aged between 3 - 9 years old. Correlates of prematurity (degree of prematurity and birth delivery route) were investigated in relationship with cortisol levels with regression analysis.

RESULTS

Corrected for sex, delivery by C-section was associated with lower cortisol levels in the children (ß = -.42, p = .028), with an explained variance of 34%.

CONCLUSION

Birth delivery route by C-section is associated with lowered (or flattened) cortisol levels in children born prematurely. This is clinically relevant and might have important implications, because an HPA-axis disturbance might lead to developmental problems later on in life. However, future research is necessary to investigate the underlying indications for performing a C-section, which will help to understand factors that influence the HPA-axis development in children born prematurely.

Follow-up care and support to parents of premature children: Multidisciplinary versus regular follow-up care

BACKGROUND

Preterm care involves clinical measures almost exclusively aimed at keeping the preterm alive and ready for discharge from hospital. Children are then enrolled in clinical follow-up care after this stressful period, but mental or specialised care for parents and child is often not embedded in the routine of a neonatal hospital ward and the family is then dependent on institutions for mental health or child health clinics, that is, regular care that is regionally scattered. This study aimed to investigate experiences of parents with regular care and compare them with parents visiting a fixed, specialised, multidisciplinary institute, outside the hospital walls, for preterm follow-up care.

METHODS

A survey was conducted among 56 parents (regular follow-up care N = 26; multidisciplinary follow-up care N = 30) of children born prematurely. The survey consisted out of items like parents' experiences with follow-up care, like the organisation of care, supportive care, environmental support and experienced stress.

RESULTS

Parents receiving multidisciplinary follow-up care reported higher levels of satisfaction with organisation of care (F = 5.45; p = 0.023) and supportive care (F = 11.69; p = 0.001) than parents receiving regular follow-up care. Also, it was found that the extent of support from the social environment alleviated stress but only in parents receiving regular follow-up care (ß = -0.47; p = 0.016).

CONCLUSIONS

The current study findings indicate that experience with follow-up care is valued higher when receiving multidisciplinary care than regular care, and the degree in environmental support alleviates stress in parents receiving regular care.
